7P HVAC Noise Issue
Hello all, I'm having a weird issue with our 2013 and was hoping someone might have an idea. I am getting a whistle/whine from the HVAC system. It has nothing to do with the actual AC, or engine. The noise happens with he car on/off, moving/sitting still.
The noise does change with fan speed, and changes a little if I play with the vents. I can change the direction of air flow (front/feet/top) and it does not matter. The other weird part is, it only happens when it's warm. It went away during the winter...
I am thinking fan blower motor, BUT, the noise sounds very central in the dash. I even changed the cabin air filter, and the noise does not sound like it is coming from the blower. So I'm stumped. Tried TONs of searches here, and on Q7 and Cayanne forums with no luck.
Anybody have an idea? Greatly appreciate any help someone can offer up.
